To all w/wm, it may concern:

Be it known that we, EDMOND CIIARPEN- TIER and JosEPn RIOI-IELLE,subjects of the King of Belgium, residing at Verviers, Belgium, haveinvented new and useful Improvements in Machines for ManufacturingMetallic Healds; and we do hereby declare the following to be a full,clear, and exact description of the same.

This present invention relates to heddles or healds for looms, theobject being to provide an improved machine for manufacturing metallichealds by means of double-wire sections. In this improved machine thewire sections are placed manually, one by one, upon two movable forksoperated to bring the same upon two suitable supports and at the sametime between several claws,which hold the wire during the formation ofthe eyes and the stitch (central eye) and during the twisting of theparts of the wire adjacent to the eyes and the stitch, certain clawsbeing adapted to slightly bend the wires at the end in order to providerecesses wherein the ends of the wire are lodged and the completed healdbeing automatically taken from said retaining-claws and brought upon asuitable conveyer and thence into any desired receptacle. The improvedmachine is provided with means for avoiding the breaking of the wireduring the twisting of the several parts thereof.

The invention consists of the construction, combination, and arrangementof parts fully described and claimed hereinafter, reference being had tothe accompanying drawings, showing the preferred form of embodiment ofthe invention, and wherein Figure 1 is a top plan view of the right-handpart of the machine. Fig 1 is a top plan view of the lefthand part ofsame. Fig. 2 is a vertical cross-section on line a a of Fig. 1. Fig. 3is a vertical cross-section on line b b of Fig. 1. Fig. 4 is a verticalcross-section on line c of Fig. 1. Fig. 5 is a vertical crosssection online (11 (Z of Fig. 1. Figs. 6 and 7 show front and side elevations ofthe plate upon which the blanks of wire are placed before they areformed to healds. Fig. 8 shows the device for conveying the completedheald. Fig. 9 is a detail view showing the device which receives theblanks one by one and brings the same to theoperating parts of themachine. Fig. 10 shows a completed heald.

Fig. 11 shows a wire blank, and Figs. 12, 13,

and 14 illustrate the different steps of manu facture.

Arranged on a frame 1, preferably made of wood or similar material andsupported on a castiron frame 2, are brackets 3 3, wherein is j ournaled the main shaft l, actuated by means of a pulley 5, through theagency of two gearwheels 6 7. Arranged above the wooden frame 1 is ametallic frame 8, provided with bearings wherein are j ournaled twocamshafts 9 10, actuated by means of the inclined transmission-shafts 1112, rotated by the toothed wheel 13 on the main shaft 4. The right-handend of the latter is preferablyprovided with a hand-motor 14, permittingof actuating the several parts very slowly for adj usting purposes.

Secured to the frame 8 is a bracket 15, the outer end of which isprovided with a socket 16, Fig. 1, corresponding to the sockets 17 17 ofa protecting-plate 18, Figs. 6 and 7, made one with a plate 19, the rimsof which are slightly bent upwardly to form a trough. A pin passedthrough the sockets 16 and 17 17 connects the brackets with the plate18, the latter then covering the operating parts of the shaft 10 and theplate 19 occupying the position shown in dotted lines in Fig. 1.

The double-wire blanks a, serving to form the healds and beingpreviously cut to the required length, are placed upon the plate 19. Theoperator takes the blanks one by one from said plate 19 and puts themupon two forks 2O 20, Figs. 1 and 9, each of which is carried by aslide-block 21, adapted to slide in a grooved piece 22, fulcrumed on apivotpin 23, secured to a bracket 24, adjustably arranged in a slot ofthe frame 8. Said slot permits of adjusting the position of the forks 2020 in accordance with the length of the healds to be manufactured. Eachfork 20 is constantly pulled backwardly that is, in the direction of thearrow 26, Fig. 1--while the outer end of each slide-block 21 isconstantly pulled downwardly by the action of a spring 27, attached tothe frame 1 of the machine. Said outer end of each slide-block 21 isformed by an arched portion 28, carrying on each side rollers 29 30, theroller 29 cooperating with the cam 31, keyed on the shaft 10, while theroller 30 cooperates with another cam 32, also keyed on said shaft 10.The latter being rotated by the transmission device above referred toand the operator having placed a blank (double-wire section) upon theforks 20 20, the latter are moved toward the interior of the machine bythe action of the cam 32, acting upon the roller 30. (See Fig. 9.)Toward the end of said movement and when the forks 20 20 are in linewith the movable supports 33, Fig. 1, the earns 31 engage the rollers 29and raise the arched ends 28 of the slide-blocks 21, so that the forks20 are lowered for depositing the blank upon the supports 33, being alsoin the shape of forks. Said supports are secured to the sides of amovable claw 34, attached to a slide-block 35, having two branchesorarms arranged to slide in grooves provided in the sides of a stationarycross-bar 36 and the ends of which carry a roller 37, engaged by a cam38, Fig. 5., keyed on the shaft 10. The roller 37 is constantly held incontact with the cam 38 by the action of two springs 39 39, Figs. 1 and5, and said cam 38 serves to move the slide-block 35, and therefore theclaw 34, with the supports 33, toward the center of the machine. Durinthis movement the claw 34 meets with and engages another claw 40,arranged to slide on the extension of the crossbar 36, already referredto, and carrying two rods 41 41, provided with strong spiral springs 42and movable in two supports 43 43, attached to the crossbar 36. When theclaw 34 is moved by the action of the cam 38, it moves also the claw 40a ainst the action of the springs 42, the blank (1 being yieldingly heldbetween said claws 34 and 40 for the formation of the heald. When theblank a is being held between the claws 34 and 40, the ends of saidblank are moved along the guiding angle-irons 51 51 after being engagedby the claws 44 44 of the coijperating pairs of claws 44 45. Each claw44 is carried by a slide-block 46, Figs. 1 and 4, arranged to slide onthe side of a stationary cross-bar 47 and carrying at its outer end aroller 48, coperating with a cam 49, fast on the shaft 10, and servingto reciprocate said slide-block 46 on said cross-bar 47, together with aspring 50, provided therefor. lVhen the cam 49 causes the slide-block 46to be moved forwardly, another cam 52, fast on the shaft 10, causesanother block 53 to be moved forwardly, said slide-block 53 beingarranged to slide on the upper side of the cross-bar 47. The slideblock53 carries a lever 54, pivotally connected at 55 with said slide-blockand held in the position shown in Fig. 1 by the action of a spring 56.The movement of the lever 54 is limited by a small slot 57, provided atthe inner end of said lever and engaged by a pin 58, secured to theslide-block 53. When the latter is moved, together with the lever 54,toward the interior of the machine by the action of the cam 52 andcarries with it the end of the blank a, a beveled extension orprojection 59 of the cam 52 will engage the outer end of the lever 54and cause the same to swing on its pivot-pin 55, so that the inner endof said lever provided with a clownwardly-projecting pin is caused toswingin the direction of the arrow 60, Fig. 1. When moved forwardly withthe slide-block 53, said lever 54 folds the end of the blank a, engaginga stud 61, secured to a piece 62, herein after described, the ends ofthe blank being thus folded to an angle of about ninety degrees. (SeeFig. 12.) When now thelever 54 is caused to swing by the action of theprojection 59 of the cam 52, the downwardly-projecting pin at the end ofsaid lever folds the end of the blank around said stud 61. (See Fig.13.) During the swinging movement of the lever 54 both ends of the blanka are caused to engage two guides 63, secured to the crossbar 47, Fig.3, and the recesses of which correspond to the openings of the forks 6464, movably arranged on said cross-bar 47 and actuated by means of twocams 65 65, fast on the shaft 9, and two springs 66 66. Said forks areguided by means of two slide-blocks 67 67, engaged by headed pins 68 68,secured to the side of the cross-bar 47. The folded ends of the blank a,enga ing the guides 63 63, the forks 64 are moved orwardly by the actionof the cams 65 and close the eyes at the ends of the blank (1. (See Fig.14.) The claws 44 being at this time in contact with the straightportion of the blankthat is, the portion adjacent to said eyes-the006perating claws 45 are moved toward said claws 44 to hold the blankduring the twisting of the eyes. At the same time a small projeotion 69,arranged on the working faces of the claws 44, engages the blank andproduces a small bend b therein, Fig. 10, serving to lodge the foldedend of the wire after the twisting thereof, so as to produce a healdwith a perfectly smooth surface. The claws 45 are each attached to aslide-block 70, formed of two parts connected by means of a rod 71,secured to one of said parts and adapted to be freely moved in theother, a coiled spring 72 around said rod serving to provide a yieldingpressure between the claws 44 and 45 and prevent the blank 60 from beinginjured by a too sudden engagement of said claws. The slide-blockcarries at its end opposite to the claw 45 a roller 73, which is held inconstant contact with a cam 75, fast on the shaft 9, by the action of aspring 74. The claws 44 45, tightening between them the blank a, theforks 64, liberated by their cams, are disengaged from the blank by theaction of the springs 66. When the forks 64 are being disengaged fromthe blank, two matrices 76, the recesses of which are somewhat largerthan the studs 61, are moved over the eyes formed at the ends of thewire a. Each matriX7 6 is adapted to slide along a square spindle 77 andis pivotally connected with a lever 78, adapted to swing on a verticalpivot-pin 79, secured to the frame 8. Theouter end of each lever 78engages the recessed side of a cam 80, fast on the shaft 9. When theends of the levers 78 engage the recesses of said cams 80, springs 81cause the opposite ends of said levers, and therefore the matrices 76,to be moved on the square spindles 77, so that said matrices are broughtover the two eyes and the studs 61 in view of the subsequent twisting ofthe wire. Prior to said twisting it is necessary to tighten the two endsof the blanks (t in an absolutely certain way and much stronger than itis possible to do with the cams 49 and 75. To this end the action of thecam is assisted by the following device: Keyed on the main shaft 4 attwo points corresponding to the positions of the claws 44 45 are twocams 82, each of which engages a lever 83, adapted to swing on a bracket84, and the upper end of which carries a stud-shaft 85, carrying apivotingarm 86, the free end of which is actuated by means of a coiledspring 87 attached to the frame 1, Fig. 3. The spring 87 causes the arm86 to constantly engage a projecting pin 88, carried by a slide-blockS9, movably arranged in a groove 90 of the lever 83. The movement ofsaid slide-block is limited by a slot 91, provided in the side wall ofsaid groove 90 and engaged by a pin 92, secured to the slide-block 70for the purpose of pushing the latter, together with the claw 45,strongly against the claw 44, when the cam 82 causes the lower end ofthe lever 83 to swing in the direction of the arrow 93, Fig. 3. The eyesformed at the ends of the blank (0 being thus engaged in the matrices 76and the wire being securely held near said eyes by the pairs of claws 4445, all that is necessary is to give some turns to each eye for twistingtogether the free ends and the straight body part of the wire. Saidtwisting movement is obtained as follows: Keyed on the square spindle77, Fig. 1, is a toothed pinion 94, at tached to a hollow socket 95,provided with a longitudinal groove 96, normally engaged by a pin 97,movable vertically in a balance lever 98, to which is pivotallyconnected at 99 a lever 100, pulled downwardly by the ac tion of acoiled spring 101, attached to the wooden frame 1, and whereby the lever100 holds the pin 97 engaged in the groove 96 of the socket 95 until thecam 102, fast on the shaft 9, is disengaged from the free end of thebalancelever 98, whereby the latter swings on its pivotal pin 103. Atthis moment a circular disk 104, keyed on the main shaft 4 and providedwith a toothed peripherical portion, the number of teeth of said portionbeing in a given relation with the number of teeth of the pinion 94, isoperated to mesh with said pinion to rotate the samethat is, impart one,two, three, or more turns to the same. The result thereof is that thesquare shaft 77 and the matrix 76, carried thereby, are rotated andcarry with them the eye of the blank a, held between the stud 61 and thematrix 76, whereby the wire portions adjacent to the eyes are twisted.(See Fig. 10.) Before said twisting of the eyes of the blank a the claws34 and 40, which already hold between them the central portion of theblank (L, as above described, are caused to produce a supplementalpressure on said blank by the action of a cam 105, keyed on the mainshaft 4 and having two operating curves 106 107, Fig. 5. The portion 106first engages a fulcruined lever 108, (similar to the lever 83, alreadydescribed,) terminating in a fork 109, the branches of which areprovided with slide-blocks 110, arranged like the slide-blocks 89, abovedescribed. Said slideblocks are provided with a beveled projecting edgeadapted to engage a corresponding horizontal recess or groove providedat the outer end of each rod 41, projecting from the supports 43 by theaction of the cam 38, actuating the claws 34 and 40, as already described. Then the cam portion 106, Fig. 5, causes the end of the lever108 to swing in the direction of the arrow 111, the slide-blocks 110 arecaused to produce a strong pressure on the rods 41, and therefore on theclaws 40, against which are pressed the claws 34. At this moment thewire portion comprised between the recesses of the claws 34 and 40 issituated in the center line of a pointed pin 112, (see detail of Fig.5,) formed within the hub of a pinion 113, provided with a hori zontalslot 114, through which the blank a is brought to said pointed pin. Saidpinion is journaled by means of its hub in a recess of the cross-bar 36.Thepointed pin is caused to penetrate between the two wire portions ofthe blank a, when the strong pressure is produced on one side by the cam38 and on theother side by the lever 108. The result thereof is that thewire portions are separated at the central part of the blank to form thecentral eyelet or stitch of the heald. (See Fig. 14.) The pointed pin112 being thus engaged between said wire portions,-the cam portion 106will be disengaged from the lever 108, which immediately thereafter isengaged by the longer cam portion 107, producing the required strongpressure between the claws 34 and 40 during the twist ing of the wireportions adjacent to said central eye. During the action of the cam 107on the lever 108 a circular disk 115, the periphery of which is providedwith atoothed portion 116 (like the disk 104) is caused to mesh with thepinion 113, then disengaged from the retaining-pin 117, carried by a balance-lever 119, actuated by the cam 118, keyed on the shaft 9. Saidbalance-lever 119 is connected with an arm 120 and similar to thatalready described for the temporary locking of the pinion 94. In thisway the pinion 113 is rotated and carries with it the central eye formedby the pointed pin 112 for twisting the wire portions adjacent. to saidcentral eye. The pressure produced by the cam 106 serves to prevent thewire portion from being unsoldered over a too large extent during thepenetration of the pin 1 12 between said wire portion. It will be notedthat the twisting of the portions adjacent to the central eye iseffected approximately at the same moment as the twisting of theportions adjacent to the extreme eyes, the toothed periphery of the disk115 being caused to mesh with the pinion 1 13 when two or three teeth ofthe disk 104 are already in mesh with the pinion 94. During the twistingof the several portions of the blank a the latter is evidently submittedto a strong tension, which could cause the break of the blank. In orderto avoid this break, it is necessary to give the parts which hold theblank during the twisting a certain longitudinal play, which is obtainedas follows: The square spindle 77 on each side of the machine carries afixed collar 121, against which presses a coiled spring 122, fittedaround said spindle, and the other end of which presses against thebearing 123 of the spindle, said bearing being stationarily arranged onan adjustable cross-bar 124 of the frame 8. In this way the tensionproduced during the twisting of the blank is en abled to move towardeach other the spindles 77 and therefore the eyelets formed at the endsof the blank a, whereby the break of the latter at the twisted portionsis effectively avoided. The longitudinal movement of the spindles isevidently of very small amplitude. The portion adjacent to the extremeand cen tral eyes being thus twisted and the several claws being againdisengaged from the completed heald, the extreme eyes must still bedisengaged from the studs 61, around which they have been formed. Thisdisengagement is obtained by the action of two cams 125, keyed on theshaft 9 (at the opposite ends of the same, Fig. 1 and engaginghorizontallyarranged levers 126, fulcrumed on adjustable pivot-pins 127,and the inner ends of which are constantly engaged with the ends of thesquare spindles 77 by the action of coiled springs 128. When the cams125 cause said levers to swing in the direction of the arrow 129, theinner ends of said levers act to move said spindles 77 toward each otherso as to decrease the distance between thestuds 61 and permit of easilydisengaging the completed heald from the same. At this moment two cams130, keyed on the main shaft 4, are operated to raise lever-arms 131,Fig. 3, pivoted on stationary pivot-pins 132 and on each'of which restsa rod 133, provided with a spring 134, and guided in a socket 135,secured to the cross-bar 47 of the frame 8. WVhen raised, the ends ofsaid rods which are arranged below the extreme eyelets of the healdraise the latter above the studs 61 in order to permit the forks of theconveyer to take the completed heald from the supporting-forks 33.

The conveying device is constructed and arranged as follows: Journaledin suitable bearings 136, arranged on the frame-8, is a shaft 137 towhich are attached the two picking-forks 138, made of an adjustablelength and adapted to take the completed heald for depositing the sameupon the conveyer proper. This comprises a pair of chainwheels 139 139,keyed on the shaft 137, and around which pass two endless chains 140,passing also around two chain-wheels 141 141, keyed on a shaft 142, journaled in bearings 143, and actuated by the shaft 9 through the agencyof a gearing 144. The picking forks 133 being rotated in the directionof the arrow 145, Fig. '8, with a heald therein are caused to depositthe heald upon two inclined guides 146, secured to the frame 8, as soonas said forks are moved rearwardly beyond the vertical line. The healdglides along said guides upon the chains 140 140, which bring the sameinto any suitable receptacle 147, attached to the frame 8.

The operating-cams 31 32 of the forks 20 have evidently an inoperatingportion which is sufficiently longto permit a blank a to be convenientlyplaced into said forks. The forks of the supports 33 are cut at a veryacute angle so as to cause the blank to engage the same in such manneras to have the wires thereof placed the one above the other. In this waythe pointed pin 112 of the pinion 113 is in any case enabled topenetrate be tween the two wires of the blank for the form ation of thecentral eye.

The operation of the several parts is clearly understood from theforegoing description, and it will be sufficient now to describe thegeneral operation of the whole machine. The blank 0. being placed intothe forks 20 the latter are moved forwardlythat is, toward the interiorof themachine-and then tipped to deposit the blank into the supports 33and between the claws 34 40, which are then moved toward each other tohold the blank during the formation of the heald. The ends of the blankengaging the studs 61, the levers 54, carried by the slideblocks 53,will be operated to fold said ends around said studs, while the forkedslide-blocks 64 are moved to close the eyes thus formed, the claws 44 45being moved toward each other to slightly bend the blank a in order toprovide recesses for lodging the extremities of the wire a. The matrices76 being now brought over the closed eyes, the several claws areactuated to produce a supplemental pressure on the blank (1, and thepointed pin 112 of the pinion 113 forms the central eye of the heald.The partially-toothed disks 104 and 115 are rotated to mesh nearlysimultaneously with the pinions 94 113,respect'ively, and produce thetwisting of the wire portions adjacent to the. several eyes, whereuponthe heald is completed. The claws are then moved apart from each otherafter the disengagement of the matrices 76 and the disengagement of theheald from the studs 61. The heald is then raised by the action of thecams 130 to be taken by the forks 138 and conveyed by the chain 140 intothe receptacle 147. The twisted portions of the heald may be smoothedsubsequently by means of solder.

The main pulley 5 is preferably provided with a coupling device, theoperating-lever of which is in the reach of the operator in order toenable the latter to stop the machine instan tly when a blank is notmoved accurately through the machine.
